This is a fantastic little game ported and improved from an original Flash version. You play a tiny micro-organism living in some kind of watery world. You swim about by tilting the ps3 controller in the direction you want to move, which is usually towards some food (ie smaller micro-organisms). As you eat more food, you grow and develop new features and can dive to deeper levels. When you hit the bottom you change into a different kind of micro-organism and start again, facing different challenges and growing in different ways. This happens a few times and then the game starts all over. It's accompanied by an excellent ambient soundtrack which is largely controlled by what you are doing (very much like the fantastic Rez), and it has a distinctive yet calming visual style. It's simple, relaxing and fun; It's not very hard and it doesn't take very long to complete. Perfect for under £4 and a few minutes of downloading.
